gilligan Posted February 4, 2022 Share Posted February 4, 2022 I’m thinking of doing it on mine. Starting off with a very fine grit like 320 and working my way up gradually to finer grit to get a nice smooth and even finish. I personally like the “road worn” look of my LSI but I think they will look pretty sharp if I can bring the trim back to what it looked like in 1987 when they were made. Any input, suggestions, comments, concerns or repudiation warmly welcomed 😎 -Gil 1 Quote Link to comment Share on other sites More sharing options...
chassell Posted February 5, 2022 Share Posted February 5, 2022 I just completed a pair of '78s that had really rough trim. I experimented with several methods. The easiest and best turned out to be a scotchbrite-type pad for my angle grinder available at Lowes. Get a couple of packs. I clamped trim to a saw horse and used the angle grinder. It's very controllable and takes the anodized layer right off. I did not try to remove all the deep gouges, but left them for character. It will leave faint swirls but I removed these polishing by hand with aluminum polish. Far easier than sanding. I was happy with my results. Also, those corner pieces aren't aluminum. They're some sort of plated metal...mine were peeling. I sanded and painted them. Plating or powder coating the corners would be options, but pricey. 3 Quote Link to comment Share on other sites More sharing options...

MookieStl Posted February 5, 2022 Share Posted February 5, 2022 I did what @chassell did on some beat to hell trim on and HIP! So beat up, the trim was given to me. I buffed with a DA sander then did the scotchbrite by hand. It is a fair amount of work but worth it. I too did not go all the way down to get the deep grooves out, but just far enough to make them look presentable. They are supposed to look "industrial"! 2 Quote Link to comment Share on other sites More sharing options...

One had a mouse-eaten woofer. @Dave Ahappened to have a K-43 so I drove down to Lynnville. I came home with the K-43, all the capacitors I needed for the AA networks and a set of tweeters. One-stop shopping. 1 1 Quote Link to comment Share on other sites More sharing options...
chassell Posted February 5, 2022 Share Posted February 5, 2022 @MookieStl I remember your HIP build. Very cool. How did you do your corner pieces? Quote Link to comment Share on other sites More sharing options...
MookieStl Posted February 5, 2022 Share Posted February 5, 2022 The corners were not that bad and did not have any coating like what you described. Mine were cast pieces and so are the ones on my LSI splits. I did buff them slightly but not much. 1 Quote Link to comment Share on other sites More sharing options...
